SOLE-ROUNDING MACHINE.

SPECIFICATION forming part of Letters Patent NO. 700,624, dated May 20, 1902.

Application filed February 14, 1901. Serial No. 47,305. (No model.)

To all whom, it may concern:

Be it known thatI, CLARENCE FJCUSHINGJ. citizen of the United States of America,and a resident of North Abington, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Sole-Trimming Machines, of which the following is a specification.

My invention relates to sole rough roun'd- 1o ing and channeling machines, and "is an improvement upon-the invention shown and described in the Letters Patent No. 645,934, issued March 27, 1900, to which reference may be had for information as to the construction,

arrangement, and operation of all the parts of the machine not shown injthe drawings forming part of this application and not referred to in detail in this specification; and my invention consists in certain novel features of.

construction, arrangement, and combinationv of parts which will be readily understood by. referenceto the description of the accompanying drawings and to the claims hereto ape pended and in which my invention is clearly pointed out.

In the manufacture of boots and shoes it is sometimes desirable to so cut or shape the sole that that portion of the sole along the outside of the fore part of each shoe shall project a greater distance from the upper than around the toe or the inside portion of the fore part, thereby forming what is known as a Baltimore edge. Many efforts have been made to accomplish this object by machinery and 3 5 several attachments have been devised for this purpose and applied to sole-trimming machines of various kinds, but as a rule the devices have been so complicated in character that very little success has attended their use.

The present invention has for its object the production of a simple and compact'device by which the objections to the devices heretofore in use may be entirely obviated, and to this end I apply to a rough-rounding machine, the 5 main portions of which are constructed substantially the same as shown and described in the before-cited patent, my improvement, which is clearly illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a roughtion,

rounding machine having my improvement applied thereto. Fig. 2 is a partial front elevation of the guide-carrying lever and my ad justable guide drawn to an enlarged scale. Fig. 3 is a vertical section of said lever on line 5 5 A A on'Fig. 2 and showingthe adjustable guide and its operating-eccentric in elevaand Fig. 4 is a vertical section of said lever and the operating-eccentric on line B B on Fig. 3 looking inthe direction of the arrow on Fig. 3 and showing the adjustable guide in elevation.

In the drawings, 1 is the frame of the head of the machine, constructed and arranged to be mounted upon a column orbench. (Not shown.) The driving-shaft 2 is mounted in hearings in said frame and has mounted thereon suitable cams for operating the crescentshaped lever 3, the cutter-bar 3 the feed-point carrying-bar 4, and the feed and cutter bar carrying pivoted plate 5, all constructed, arranged, and operating as in said before-citedpatent,thelever3,throughaguide which it carries and which will be hereinafter described, being laterally movable and cooperating with the work toimpart to it a feeding movement with relation to the cutter. The front or short arm of the lever 3 is bifurcated to form two downwardly-projecting arms 6 and 7, the inner faces of which have formed therein rectangular grooves 8 and 9, respectively, in which is fitted, so as to be vertically movable therein, the gage-plate or guide 10, having out therethrough the rectangular slot 11 and the L-shaped slot 12, as shown in Figs. 2 and 4. The arms 6 and 7 have fitted to suitable bearings therein a shaft 13, having fixed thereon between said arms the eccentric disk 14, having on one side thereof the laterally-projectin g lip 15,extendin g nearly around said eccentric at its periphery and arranged to engage the L-shaped slot in said plate, as shown in Fig. 4. The shaft 13 has fixed thereon outside of its hearings in the arms 6 and 7 a lever 16, by which said eccentric may be moved about its axis to a limited extent to raise or depress the gage-plate 10 at the will of the operator. The lever 16 may be provided with ahandle at its upper end, as shown in Fig. 1, and operated by hand, or its movable cnd may be connected in any well-known manner to a treadle (not shown) and be op erated by the foot of the operator. The lever 3 has secured thereto on the side thereof next to the lever 16 the segmental plate 17, in which are formed a series of holes 18, in which are interchangeably set two pins 19, which serve to limit the movement of said lever 16 in either direction, as shown in Fig. 1. The

inner surface of the lower portion of the gageplate 10 is serrated or roughened to give a firm hold on the surface of the sole when the shoe is being fed.

The frame 1 has secured thereto in a fixed position a bracket 20, the lower portion of which projects outward through the slot 11 in the gage-plate 10 and downward to a point below the trimming-cutter and has secured to the inner surface of its lower portion a softmetal plate 21, against which said trimmingcutter contacts after passing through the sole precisely as described in said before-cited patent.

The operation of myinvention is as follows: The gage-plate 10 being in the position shown in Fig. 1 and a left shoe being placed in position, with its toe toward the right, and said gage-plate entering the crease between the sole and upper, with its inner surface bearing against the welt and the machine being set in motion, the machine operating substantially as described in said prior patent will trim the sole edge to a uniform distance from the upper. If, however, it is desired to vary the projection of the sole to form what is known in the trade as a Baltimore edge, the operator when the shank has been trimmed moves the lever 16 toward the rear, thereby rotating the eccentric l4 and moving the gageplate downward transversely to the direction of movement of the knife, thus forcing the shoe downward and causing the cutter to act upon the sole at a greater distance from the junction of the upper with the sole. The movement of the lever 16 may be gradual until it is arrested by the lever stop-pin 19, and when the trimming has reached a point a short distance from the curve of the toe the lever 16 is gradually moved in the opposite direction until arrested by the upper pin 19, when the toe and the other side of the sole edge will be trimmed without further adj ustment of the lever 16 and the gage 10.

The amount of variation in the projection of the sole edge may be regulated by moving one or both of the pins 19 to greater or less distance from the end of the segmental plate 17, thereby varying the amount of vertical movement to be given to the gage-plate 10.

It will be seen that the gage-plate or guide and its entire adjusting mechanism are carried by and moved with the feeding-lever, which, in addition to its feeding function, thus acts as a guide-support, permitting my improved Baltimore-edge attachment to be applied to rough-rounders of this type with merely simple changes to a single element.
